| 988 | * A PyArg_ParseTuple "converter" function | ||
| 989 | * that handles filesystem paths in the manner | ||
| 990 | * preferred by the os module. | ||
| 991 | * | ||
| 992 | * path_converter accepts (Unicode) strings and their | ||
| 993 | * subclasses, and bytes and their subclasses. What | ||
| 994 | * it does with the argument depends on the platform: | ||
| 995 | * | ||
| 996 | * * On Windows, if we get a (Unicode) string we | ||
| 997 | * extract the wchar_t * and return it; if we get | ||
| 998 | * bytes we decode to wchar_t * and return that. | ||
| 999 | * | ||
| 1000 | * * On all other platforms, strings are encoded | ||
| 1001 | * to bytes using PyUnicode_FSConverter, then we | ||
| 1002 | * extract the char * from the bytes object and | ||
| 1003 | * return that. | ||
| 1004 | * | ||
| 1005 | * path_converter also optionally accepts signed | ||
| 1006 | * integers (representing open file descriptors) instead | ||
| 1007 | * of path strings. | ||
| 1008 | * | ||
| 1009 | * Input fields: | ||
| 1010 | * path.nullable | ||
| 1011 | * If nonzero, the path is permitted to be None. | ||
| 1012 | * path.allow_fd | ||
| 1013 | * If nonzero, the path is permitted to be a file handle | ||
| 1014 | * (a signed int) instead of a string. | ||
| 1015 | * path.function_name | ||
| 1016 | * If non-NULL, path_converter will use that as the name | ||
| 1017 | * of the function in error messages. | ||
| 1018 | * (If path.function_name is NULL it omits the function name.) | ||
| 1019 | * path.argument_name | ||
| 1020 | * If non-NULL, path_converter will use that as the name | ||
| 1021 | * of the parameter in error messages. | ||
| 1022 | * (If path.argument_name is NULL it uses "path".) | ||
| 1023 | * | ||
| 1024 | * Output fields: | ||
| 1025 | * path.wide | ||
| 1026 | * Points to the path if it was expressed as Unicode | ||
| 1027 | * and was not encoded. (Only used on Windows.) | ||
| 1028 | * path.narrow | ||
| 1029 | * Points to the path if it was expressed as bytes, | ||
| 1030 | * or it was Unicode and was encoded to bytes. (On Windows, | ||
| 1031 | * is a non-zero integer if the path was expressed as bytes. | ||
| 1032 | * The type is deliberately incompatible to prevent misuse.) | ||
| 1033 | * path.fd | ||
| 1034 | * Contains a file descriptor if path.accept_fd was true | ||
| 1035 | * and the caller provided a signed integer instead of any | ||
| 1036 | * sort of string. | ||
| 1037 | * | ||
| 1038 | * WARNING: if your "path" parameter is optional, and is | ||
| 1039 | * unspecified, path_converter will never get called. | ||
| 1040 | * So if you set allow_fd, you *MUST* initialize path.fd = -1 | ||
| 1041 | * yourself! | ||
| 1042 | * path.length | ||
| 1043 | * The length of the path in characters, if specified as | ||
| 1044 | * a string. | ||
| 1045 | * path.object | ||
| 1046 | * The original object passed in (if get a PathLike object, | ||
| 1047 | * the result of PyOS_FSPath() is treated as the original object). | ||
| 1048 | * Own a reference to the object. | ||
| 1049 | * path.cleanup | ||
| 1050 | * For internal use only. May point to a temporary object. | ||
| 1051 | * (Pay no attention to the man behind the curtain.) | ||
| 1052 | * | ||
| 1053 | * At most one of path.wide or path.narrow will be non-NULL. | ||
| 1054 | * If path was None and path.nullable was set, | ||
| 1055 | * or if path was an integer and path.allow_fd was set, | ||
| 1056 | * both path.wide and path.narrow will be NULL | ||
| 1057 | * and path.length will be 0. | ||
| 1058 | * | ||
| 1059 | * path_converter takes care to not write to the path_t | ||
| 1060 | * unless it's successful. However it must reset the | ||
| 1061 | * "cleanup" field each time it's called. | ||
| 1062 | * | ||
| 1063 | * Use as follows: | ||
| 1064 | * path_t path; | ||
| 1065 | * memset(&path, 0, sizeof(path)); | ||
| 1066 | * PyArg_ParseTuple(args, "O&", path_converter, &path); | ||
| 1067 | * // ... use values from path ... | ||
| 1068 | * path_cleanup(&path); | ||
| 1069 | * | ||
| 1070 | * (Note that if PyArg_Parse fails you don't need to call | ||
| 1071 | * path_cleanup(). However it is safe to do so.) | ||
